Originální abstrakt

The paper deals with significance testing of wavelet coefficients. We investigate the test of wavelet power spectrum with respect to the Gaussian white noise background spectrum from two perspectives of calculating significance level: with the use of chi-square distribution and with the use of Monte Carlo simulation. Our experiment is performed on a special kind of synthetic signal in which the frequency component is changing during time. We investigate the level of variance of the signal and the significance risk. We describe the advantages and disadvantages of both approaches and formulate recommendations for using time-frequency testing.
